DC-input PD schemes not covered by items 1~3 above:
For input beyond 5V~31V, or output voltage/power/port count outside items 1~3, use a conventional DC-DC converter (BUCK, BOOST or BUCK-BOOST) plus a PD protocol controller:
If input is below 5V, refer to Boost Circuit Design + PD Power Secondary-Side Circuit Design.
If input is above 30V, refer to Buck Circuit Design + PD Power Secondary-Side Circuit Design.
For other cases refer to Buck-Boost Circuit Design + PD Power Secondary-Side Circuit Design.
